hero-- a vigil that's about to come to an end. here's steve hartman with tonight's "assignment america." >> reporter: while the war raged in vietnam, back home these became all the rage. metal bracelets sold by the millions, each bearing the name of a soldier who was either stale prisoner in vietnam or missing in action. the idea was to wear the bracelet and only take it off when your vet came home. the bracelets were especially popular with kids. like that 12-year-old girl from fremont, california, who got a bracelet in her christmas stocking in 1972. do you remember getting it? >> i was excited, i put it on right away, read the piece of paper that came with it and i thought "i'll keep it on until he comes home." >> reporter: kathy strong, now 50, still remembers the name, too, james moreland. he was a green beret that has been stationed in lang vei.
